Inventor's high hopes for air seal pistons

AN invention with potential to dramatically change internal combustion engines worldwide is being developed by a Warrnambool-based company.

It uses pistons with air seals instead of the conventional steel rings that have been in vogue since the early days of petroleum-powered engines.

The invention of 67-year-old Colin Young, who was born and educated in Warrnambool, the device is being fine-tuned by Warrnambool engineer Brian Trigg and his team at Dynex, of which Mr Young is a key member.
